1 Initial Corpus generation

1.1 Corpus Creation

Scopus download of documents retrieved from search string from Markard et al. (2012). Limited to LANGUAGE = ENGLISH AND TYPE = (ARTICLE).
Selecting “seed” publications. 1% most cited per year. Ex-post manual exclusion. Results in 53 seed papers
Retrieving for each seed 1000 publications with most shared references. Again, same limitations as in step 1.
Adittional ex. post filtering. First, based on citations recieved and connectivity in bibliographic coupling network. Namely, I excluded edges in the bottom 10% quantile of the weight distribution (Jaccard weighted), also unconnected and nodes in the bottom 10% of the degree distribution. Lastly,after the community detection exercise, I excluded nodes in communities of less than 500 members.

That leads to an overall corpus size of:

## Number of unique publications in the final corpus:  9063

1.2 Seed Paper

In the following, we more in detail investigate the seed papers.

1.2.2 Seep papers and corpus size

Generally, 50 x 1000 = 50.000 documents downloaded. However, due to an overlap of publications with most shared references to seed papers, final corpus is smaller.

First insight: It appears the main Sustainability corpus seems saturated, expansion appears more in adjacent fields.

2.3.1 Authors, Themes & Journals

3 Topic modelling

I by now created some topic modelling. The results are now more fine-tuned, but there is still room for some improvement. We ran a LDA on the titles + abstracts of our corpus, aiming at identifying 10 topics (some different numbers of topics to generate shows that 10 result in good results, more topics lead to too much overlap between them)

3.1 Topics by topwords

This might still be finetuned, but initially doesnt look that bad I think. All the topics for me seem to be somewhat identifiable. We should maybe start naming them to make their interpretation later easier.

3.2 Topics over time

3.3 LDAViz

Here you find a nice way of exploring topics via the LDAVIz methodology of visulizing the result of an LDA. It dispolays all topics in a 2 dimensional TSNE (similar to PCA, but optimized for graphical illustration in 2d), and also gives a nice visual representation over the topics top-word distribution and overall frequencies of this words in the corpus. The \(\lambda\) parameter regulates the importance-ordering of the topwords. High \(\lambda\) order words by the highest propability to appear in the topic to the lowest (independent of the overall word popularity in the corpus), whle low \(\lambda\) emphasize words which are very specific to the topic, and rarely appear in others.

Play a bit around. Since it would be here a bit condensed, better check it out HERE in fullscreen for a better overview.

4 Knowledge Bases: Co-Citation network analysis

Note: This analysis refers the co-citation analysis, where the cited references and not the original publications are the unit of analysis. See tab Technical descriptionfor additional explanations

4.1 Knowledge Bases summary

4.1.1 Main Indicators

In order to partition networks into components or clusters, we deploy a community detection technique based on the Lovain Algorithm (Blondel et al., 2008). The Lovain Algorithm is a heuristic method that attempts to optimize the modularity of communities within a network by maximizing within- and minimizing between-community connectivity. We identify the following communities = knowledge bases

It is not the main focus of this exercise, but still informative to see which historical knowledge the fields draws from.

NOTE: Up to now I only report the most central emmbers per community

4.1.2 Development of Knowledge Bases

TO BE DONE AGAIN

4.2 Technical description

In a co-cittion network, the strength of the relationship between a reference pair \(m\) and \(n\) (\(s_{m,n}^{coc}\)) is expressed by the number of publications \(C\) which are jointly citing reference \(m\) and \(n\).

\[s_{m,n}^{coc} = \sum_i c_{i,m} c_{i,n}\]

The intuition here is that references which are frequently cited together are likely to share commonalities in theory, topic, methodology, or context. It can be interpreted as a measure of similarity as evaluated by other researchers that decide to jointly cite both references. Because the publication process is time-consuming, co-citation is a backward-looking measure, which is appropriate to map the relationship between core literature of a field.

5 Research Areas: Bibliographic coupling analysis

This is arguably the more interesting part. Here, we identify the literature’s current knowledge frontier by carrying out a bibliographic coupling analysis of the publications in our corpus. This measure uses bibliographical information of publications to establish a similarity relationship between them. Again, method details to be found in the tab Technical description. As you will see, we identify the more narrow research community of Sustainability Transitions (in which we will zoom in later), but also a set of adjacent research areas with some theoretical/methodological/application overlap.

5.1 Research Areas main summary

5.1.1 Main Characteristics

To identify communities in the field’s knowledge frontier (labeled research areas) we again use the Lovain Algorithm (Blondel et al., 2008). We identify the following communities = research areas.
